Combined WAN aggregation technique Optimizing network traffic through dual connections
Combined WAN aggregation technique Optimizing network traffic through dual connections
The approach involves renting a box in a datacenter with a symmetrical 2G connection (preferably more), then using a custom VPN router that splits your WAN into two streams passing through the datacenter box, which then merges them back and acts as a single exit node. This method isn’t practical unless you have significant funds; instead, consider a dual-WAN router with load balancing so multiple devices can download simultaneously.
Consider building your own DIY router like a nanopi or choose a ready-made model that includes this feature. Apparently, some premium Asus routers already offer it. In practice, most modern tasks rely on several connections, allowing you to distribute the load across them easily. I use an ARM router connected to two 500Mbps links from different providers; it handles both failover and load balancing effectively.
Most programs needing high bandwidth rely on several connections. Whether it's torrents, Steam, or accessing content from CDNs. For lighter apps, like opening a PNG file, does downloading speed at 100MBps really matter compared to 1000MBps? Latency often plays a bigger role than bandwidth. Having multiple connections to one destination is completely possible.
You're able to use these tools, and they come from your own device. It's possible to have several connections from different machines, with load balanced across them, but a single IP address (based on the hash) will go to one uplink for the stream. This is quite different from distributing load per packet, which is much harder and needs both ends to handle it reliably.
It really doesn't matter much. My desktop can establish several links to my router, which in turn connects to the target if possible. Remember that load-balancers and CDNs exist, even though they appear to represent a single IP address—they are actually multiple ones. For basic HTTP tasks, you can still perform split downloads or uploads to improve performance, as long as the server allows it. Multi-path TCP has been around for a while now. Yes, I'm not referring to the specific scenario, but to having genuinely different connections. As mentioned earlier, most bandwidth-intensive applications depend on real separate connections, since that also enables smoother multi-threading and boosts both network and disk throughput.
